- Discovery of Novel pERK1/2- or β-Arrestin-Preferring 5-HT1AReceptor-Biased Agonists: Diversified Therapeutic-like versus Side Effect Profile
-
Novel 1-(1-benzoylpiperidin-4-yl)methanamine derivatives with high affinity and selectivity for serotonin 5-HT1A receptors were obtained and tested in four functional assays: ERK1/2 phosphorylation, adenylyl cyclase inhibition, calcium mobilization, and β-arrestin recruitment. Compounds 44 and 56 (2-methylaminophenoxyethyl and 2-(1H-indol-4-yloxy)ethyl derivatives, respectively) were selected as biased agonists with highly differential "signaling fingerprints"that translated into distinct in vivo profiles. In vitro, 44 showed biased agonism for ERK1/2 phosphorylation and, in vivo, it preferentially exerted an antidepressant-like effect in the Porsolt forced swimming test in rats. In contrast, compound 56 exhibited a first-in-class profile: it preferentially and potently activated β-arrestin recruitment in vitro and potently elicited lower lip retraction in vivo, a component of "serotonergic syndrome". Both compounds showed promising developability properties. The presented 5-HT1A receptor-biased agonists, preferentially targeting various signaling pathways, have the potential to become drug candidates for distinct central nervous system pathologies and possessing accentuated therapeutic activity and reduced side effects.

- Identification of N-(2-Phenoxyethyl)imidazo[1,2-a]pyridine-3-carboxamides as New Antituberculosis Agents
-
A series of imidazo[1,2-a]pyridine carboxamides (IPAs) bearing an N-(2-phenoxyethyl) moiety was designed and synthesized as new antitubercular agents. Seven 2,6-dimethyl IPAs demonstrated excellent in vitro activity (MIC: 0.025-0.054 μg/mL) against the drug susceptive H37Rv strain and two clinically isolated multidrug-resistant Mycobacterium tuberculosisstrains. Compound 10j displayed acceptable safety and pharmacokinetic properties, opening a new direction for further development.

- Synthesis of new (arylcarbonyloxy)aminopropanol derivatives and the determination of their physico-chemical properties
-
Eight hydrochlorides of 3-{2-[(2/4-fluorophenoxy)-ethylamino]}-2- hydroxypropyl-4-alkoxybenzoates and four hydrochlorides of 3-tert-butylamino-2- hydroxypropyl-4-butoxybenzoates were prepared as potential antagonists of the β1-adrenergic receptor (beta-blockers). A multistep synthesis of these compounds is described as well as their detailed analytical characterization. The pharmacokinetic properties of these weak base compounds are significantly influenced by their acid-base dissociation constant, pK a. The knowledge of this value is crucial for new drug development. This paper is aimed at developing a methodology that utilizes pH-dependent 1H NMR spectroscopy for its routine analysis. The selected predicted physico-chemical parameters of the new (arylcarbonyloxy)aminopropanols (i.e., aryloxyaminopropanol derivatives) were compared with the model drugs esmolol and flestolol.

- Development of a scalable synthesis of a nonbasic inhibitor of the serine protease tryptase
-
A chromatography-free process for the synthesis of a bis(benzimidazole)difluoromethane inhibitor of the serine protease tryptase is described. This synthesis features the introduction of the gem-difluoro moiety using the electrophilic fluorinating reagent N-fluoro-bis(phenylsulfonimide) as well as the stepwise introduction of both benzimidazole rings. A protocol for the destruction of reactive, process-related substances produced in the synthesis is also presented.
